Excelitas introduces the VTH21 Series photodiodes for radon gas detection

Excelitas Technologies Corp introduces its new VTH21 series photodiodes for radon gas detection. Ethelida's low capacitance VTH21 silicon photodiode series provides the best alpha particle detection in chip form and is highly responsive to associated radiation, making the new photodiodes an ideal solution for radon gas detection and alpha particle detection.

These photodiodes have a robust chip design, come in waffle disc or Mylar film (preferred) packaging, and are available in two different specifications of standard chips with larger effective areas of 5x5mm (VTH2110) and 10x10mm (VTH2120) and spectral responses between 400 nm-1100 nm.

The product is available in nude form to maximize signal levels, and the flexible size design of the product can be tailored to the specific needs of customers to provide maximum signal in alpha particle detection system applications.

Features and advantages of VTH21 series photodiodes:

● Naked chips for direct detection of alpha particles increase the amount of absorption and have better performance than packaged devices

● Rugged radiation-resistant design ensures long-term operation in the field

● The optimized chip design has greater absorption of alpha particles, so the system has higher performance

● The large area chip improves the detection rate in low signal environment and improves the system performance

● Assemblies compatible with electrically conductive epoxy resin mounting

● Provide customized services

● Meet RoHS standard

"We are pleased to introduce the new VTH21 series photodiodes for radon gas detection," said Denis Boudreau, Product Leader, Excelitas Detection Technologies. Thanks to the robust chip design of this series, low-capacitance silicon photodiodes are highly responsive to associated radiation without a radiation-absorbing window. As such, they are the best choice for alpha particle detection instrument design engineers, enabling customers to integrate photodiodes into their systems at the highest signal levels and cost performance."
